A Study of ABT-751 in Patients With Non-Small Cell Lung Cancer

A Phase II Study of ABT-751 in Patients With Non-Small Cell Lung Cancer Refractory to Taxane Regimens

The purpose of the study is to determine if ABT-751 will decrease tumors, and determine how long the tumor shrinkage can be maintained in patients with non-small cell lung cancer. Patients will receive ABT-751 by mouth daily for 21 days. Patients will be off drug for 7 days before starting the next cycle of drug.
